It's as if you have bought a Ferrari that you want to park in your garage, and you realise that your garage isn't exactly the right size to fit a Ferrari because you didn't have a Ferrari before. We discovered the problem a little late … we are making our mea culpa. Putting this network of new generation and larger trains in order to satisfy public demand will require the modernisation of 1,300 platforms out of the 8,700 in the French rail network

That's my thought. In the next years and decades the average height in Asia will increase further, likely to reach levels of Europe or US. It makes a difference whether someone has 50cm headroom or only 35cm. Not to mentioned door frames. And a tunnel is not widened over night to accommodate different types of trains.
